Baltimore Woods Nature Center covers 182 acres in Marcellus, with six-plus miles of trails (Valley, Boundary, Field-to-Forest, and Lookout). The John A. Weeks Interpretive Center houses live animals, a nature library, and the monthly Winter Farmers Market, plus a gift shop with regional crafts. Summer day camps, guided walks, school programs, and a year-round event calendar run out of the center. Dogs are not permitted. Free admission to trails; a modest donation supports the nonprofit. Closed Sundays.
